Be it known that 1, EDWIN PYNoi-ION, a citizen of the United States, anda resident of Chicago, in the county of Cook and State of Illinois, have invented anew and useful Car-Axle Lubricator, of which the following is a specifioation.

My invention relatcs to car-axle lubrioators, and has for its object to provide alubricator which may bc capable of adj ustment to fit any ordinarily-sized box,which is provided with a single lubricating-roller and an oil-conveyer, and has certain other features hereinafter described.

My invention is illustrated in the accompanying drawings, wherein- Figure 1 represents a plan View of my device when in a position for introduetion to the box, and a part-sectional view of the lubricating-roller. Fig. 2 is a Vertical section of the same through the middle thereof on the line a' x. Fig. 3 is a part-sectional view through the lineg/y, showing' the lubricator in use. Figs. 4 and 5 are detail views of a modification of my device, whereby the lubricator is made to fit any sized box. Fig. G is a detail view of the lubricating-roller.

Like parts are indicated by the same letter in all the figures.

A is a car-axle box, and B the axle.

C is a base, upon which the Operating parts of my lubricator rest. On this base is raised the standard D, on which is secured the transverse rod D', about which is wound the spring D2, having the ends D3 D3, which carry the hangers D*, upon which is pivoted the lubricating-roller D5. This lubricating-roller is provided with a central tubular aperture, DG, through which passes the rod D7, encircled by the spiral wire DS. The roller has a central core, D9, with apertures D10, and also carries lubricant-carrying material, as D. The wire D2 has the Curved end E. On the standards D is secured the frame F by the pivots G, and this frame has the projecting ends H, cross-bar I, and cross-rod J. The cross-rod'J bears against the end E of the spring D2 and rests in the angle thereof. The rod D7 passes, as shown in Fig. 1, below the base and through the central aperture in the roller at a point below the standard, and earries the rollers K K. This keeps the Wire slightly elevated above the bottom of the box. The wire D* is straightened out at one point, as shown in Figs. 1 and 2, within the tubular cavity in the roller and passes under the keeper L. It may also be secured by a piece of Wire, M, which passes between its folds, so that as the roller rotates about the rod D7 the wire will be caused to rotate about the rod.

N N are cross-rods to form the roller and assist in securing the lubricant-carrier in position.

O O are wires for the same purpose. In the modification shown in Figs. 4 and 5 the snpporting-wire D2 is inverted, and its end E is below instead of above the rod upon which it is supported. The frame F in these modifications is replaced by the frame R, pivoted at S, having the cross-piece T, the ends U,and the foot-piece V.

K2 is a pin between the Wheels or washers K to keep them from moving along the rod. The ends of the wire on which the roller is suspended are held together by a cross-Wire, as shown.

The use and operation of my invention are as follows:

Vhen it is desired to introdnce the device into a car-axle box, the extension-frame as it may be called, F or R, is folded in toward the roller, as shown in Figs. 2 and 4. In this manner the length of the base is materially reduced, while by tnrning` this extension-frame out, as shown in Figs. 3 and 5, the base may be lengthened to any ordinarily desired length. The ends U and H of the frame can of course be of any desired length. The object of this structure is to permit of the device being easily folded, so ,as to occnpy a small space when stored or shipped, and particularly to permit of its being,` folded so as to be easily introduoed through the opening into the box, and when it has been introdueed by folding of the extension-frame, the same having` been made of a size to correspond with the box to which the lubricator is to be applied, by extending the extension-frame the lubricator will be made to exactly fit the box, as shown in Fig. 3, so as to prevent it from sliding about therein. The further object of this extension-frame is, in conjunction with the IOO spring D2 and its parts, to elevate the roller in position for use. When the extension is folded toward the roller, as shown in Figs. 1 `and 2,

the spring D2 is relaxed, its ends D3 fold down- Ward toward the base, and the roller rests upon the base, thus leaving the lubricator folded Without the application 'of pressure to hold it in that position while it`is beingintroduced or s'hipped or packed. Now, when the extension-frame is folded about its pivot for the introduction of the lubricator into the box, its rod J, or, in the modification, its end T, rolls upon the extended end E of the spring D2, applies the tension to the spring, causes the same to slightly turn on its supporting-shaft D', and thus raises the arms D3 D3, and with them the roller, to the desired height. By this means a single springsupport is all that is 'required to elevate the roller, and by this spring being applied through its two arms to each end of the roller the latter is capable of being unequally, depressed at its opposite ends 'to acoommodate itself to the somewhat-irregular'motion or shape of the axle. When the roller is thus raised to the axle, as shown in Fig. 3, it is supported on the hangers D4, thus giving it an easy oscillatory motion to accommodate itself to the motion of the axle. The oil is poured into the bottom of the box, and there surronnds and, according to the quantity, covers the base and also a' portion of the -lubricator, so that the rod D7 and spring Da are partially immersed therein. Now, When the car is set in motion, the rotation of the axle causes the roller D5 to rotate, and since the Wire DS, which passes through said roller, is secured thereto, the rotation of the roller will cause the Wire to rotate about its central rod, D7, thus'causing said Wire to act as a conveyer or Archimedean pump, carrying the oil up one side and into the tubular aperture within the roller. Here the oil passes through the apertures D10 in the central core, D, of said roller, and thence out into the lubricant-carrying ma terial, saturating the same and causing it to keep the axle constantly supplied with oil. When the motion of the car is reversed, the roller will operate 'in the opposite direction and the oil will be similarly conveyed upward along the opposite portion of its supportingrod.

The lubricant-carrying material should be sufiiciently loose on the roller to permit of the passage of the oil through it. In the modification the extension-frame R is used in a similar manner to the extension-frame E, as shown in Figs. 1 and 2, except that it lies in the bottom of the base instead of at the top thereof. I have contemplated the application of this conveyer-Wire to several different though similar constructions-as, for instance, by putting it on the inside of a tubular conveyer or 'by constructing it in such manner as that neither tube nor rod will be necessary; but I think the form shown is thev best.

The application of the lubricator is very the axle. By the operation of the axlethe roller is' rotated, and the wire conveyer introduces the oil into the int-erior of' the lubr1cat By the same movement the roller is elevated against ing-roller, whence it is sent through the lubricant'carrier to the car-axle.

Having thus tlescribed my invention, what I claim, and desire to secure by Letters Patent, is as follows:
